This topic comes up pretty often. It all boils down to the fact that the core strings in the game are copyright and we can't host them online in order for people to translate. The way we are working at the moment is assisting translators will extracting strings locally and sending in the translations.

Hello EvilGenius, I had to remove the greek.lua that you attached as the file contained text from the game that is under copyright (the untranslated parts), however don't let this discourage you! keep on translating, we are looking forward to seeing the finished product!
